What is Date Coding?
Date coding involves labeling products with production or expiration dates to inform consumers about their freshness and safety. This practice is vital in maintaining product quality, ensuring compliance with regulations, and providing traceability across various industries. Linx expiry-date printers are designed to deliver precision and reliability, meeting the needs of modern manufacturers.
Types of Date Codes
- Use-by Dates: Indicate the final date for safe consumption. Products should not be used beyond this date.
- Best Before Dates: Reflect the optimal quality period of a product. The product may still be safe after this date, but its quality may diminish.
- Lot Numbers: Unique identifiers that enhance traceability and support recalls or batch tracking.
- Freezing Dates: Specify the date of freezing to ensure safety and quality during storage.
Is Date Coding a Legal Requirement?
In England and Wales, pre-packed foods must display either a use-by date or a minimum durability date, such as “best before” or “best before the end.” Additional markings like lot numbers and freezing dates are also required for regulatory compliance.

Best Before & Expiry Date Printers
Linx industrial date coding machines have pre-programmed and customizable date and time formats to match every customer need.
Using real time clock functions our date coders automatically calculate and print best before, manufacture or expiry dates. It can add a fine level of detail to your expiry date coding.
If you need expiry dates that are easily readable for your consumers or “closed dating” for meeting regulations on product traceability Linx can meet your specific printing or marking needs.

How Date Coders Make Life So Easy
The food industry isn’t the only industry that uses date coders. Date coding is used in the pharma industry, cosmetic industry, and electronic and beverage industry. Each industry has a different working environment, which these coders need to be robust enough to withstand those conditions. The coder must also be versatile enough to print on a range of different substrates, from glossy boxes to plastic film.
To handle this sort of variety, Linx has a wide range of date coders and inks to make the process easier for businesses in all industries.
Types of Date Code Machines
Our best-before-date printer uses simple on-screen prompts; templates can be easily created and stored in the internal printer memory. The date coder can also be set to variable intervals for forward or back sequential numbering, with models that auto-adjust for daylight savings time.
